Question

normal microbiota provide protection from infection in each of the following ways except a. they produce antibacterial chemicals. b. they compete with pathogens for nutrients. c. they make the chemical environment unsuitable for nonresident bacteria. d. they can change the ph of the environment. e. there are no exceptions, all the above are true.

Answer 1

For the above question, option E is the correct answer: there are no exceptions, all the above are true.

Protection against infection is provided by proper microbiome. They create compounds that are antimicrobial. They compete for nutrients with pathogens. By altering the chemical environment, they render nonresident bacteria unsuitable. They have the ability to alter the environment's ph. Thus all the statements are true.

By activating immune responses, metabolically keeping pathogens out of their favoured habitats, and directly combating microbes, the microbiota defends against infection. A significant risk factor for bacterial pathogen colonisation is the disruption of the microbiota, particularly by antibiotics.
